  • Patent number: 9402631
    Abstract: A multiple band endoscopic ligation device comprises a single pull string and a plurality of beads positioned on said pull string and between each successive band. The device is configured to be coupled to the distal end of an endoscope and is used to deploy multiple elastic bands around target tissues to be ligated. The device includes a tapered cylindrical body about which a plurality of elastic bands are stretched and positioned. The pull string includes multiple sets of two beads fixed to the string wherein one bead is placed directly behind and in contact with the other. The string is wrapped around the device's body and under each band such that at least one pair of beads is positioned between the elastic bands and one pair of beads is positioned proximally to the most proximal band. As the string is pulled, the beads push the bands sequentially off the distal end of the device and around a tissue to be ligated.

  • Patent number: 9402983
    Abstract: A variably expanding balloon catheter comprises a sequentially stepped outer shell when fully inflated, such as three sequentially increasing steps followed by three sequentially decreasing steps. For example, a balloon catheter comprises a sequentially stepped outer shell, when fully inflated, such that a first section of the outer shell is constrained to a first diameter by the sequentially stepped outer shell, and a second section, adjacent to the first section and attached to the first section by a step transition. The step transition provides a discontinuous change in diameter from the first diameter to the second diameter along a length of the balloon catheter, which may be abrupt.
